Tindie Weblog | Nifty QTPy Breakout Board


LandBoards has come out with one other nifty, compact breakout board — this time for the XAIO/QTPy boards from SeeedStudio/Adafruit respectively. The boards themselves are so tiny that having a provider board to energy and get away some I/O is a good way to broaden their usability.

The breakout sports activities a DC barrel jack that may settle for 7-15V (there’s a 5V regulator on-board) plus an SD card breakout that’s wired to the SPI pins on the microcontroller. Regardless of having these extra options, it’s nonetheless a tiny 49x49mm! With 4x 4-40 mounting holes, it’s straightforward to completely connect to a mission or use as a wearable system.

For these of you not acquainted with these boards, they pack numerous punch in a tiny bundle; the XIAO and authentic QTPy have the Microchip SAMD21G18 ARM Cortex-M0+, and the newer QTPy 2040 has the dual-core Raspberry Pi chip that appears to be slowly taking on your entire market! One of many nifty issues about these boards is they’ll run MicroPython/CircuitPython or they are often programmed with the Arduino bootloader after which be programmed from the Arduino IDE. With the SD card breakout, this board may even run MMBASIC to get a retro-computing setting going!

LandBoards additionally produce a model with out the SD card socket, as an alternative breaking out the SPI pins to an extra header in case your mission requires it. This nifty little breakout board is a good way to get began with the RP2040 or MicroPython normally!
